"Recently serviced, calibrated, and upgraded by Analog Synth Service (early 2020) in Oakland, CA

So this OB1 has better-than-original functionality, as it has the upgraded Tauntek Programmer board, which adds the following features to an already powerful synth:
1) 64 programs (8 banks w/ 8 programs each)
2) Programs are stored in non-volatile EEPROM. No battery needed. YAY!
3) After a program is loaded, only controls that have moved are "live", so patch editing is now possible
4) Manual mode forces all controls to be "live"
5) Comes with 24 pre-programmed patches, which can be over-written later if you chose
6) 20-turn trimpot for easier one-time oscillator tuning adjustment"
